APPARATUS FOR PAINTING.

SPECIFICATION forming part of Letters Patent No. 623,307, dated April is. 1899.

Application filed October 3, 1898. Serial No. 692.47 1. \No model.)

In rtZZ whom, it 777/(bZ/ concern:

Be it known that 1, JOHN H. DAVIS, a citizen ofthe United States of America, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Apparatus for Painting, of which the following is a specification.

My invention relates to the method of and apparatus for paintingdeseribed in my Letters Patent, dated January 31, 1899, No. 618,788, and, has particularreference to the means for feeding the paint upon the supporting liquid.

The main objects of my present invention are to provide for making the films or coatings which are formed upon the supporting liquid of different variegated and mottled designs and to provide for controlling the general character of the design on each film. I accomplish these objects by the apparatus illustrated in the accompanying drawings, in which Figure 1 is a top plan of a device embodying my invention, and Fig. 2 is a partly-sectional elevation of the same.

The tank 27 for containing the paint-supporting liquid is shown mainly broken away, and the surface of the liquid is indicated by the line a.

The paint pots or receptacles 2 are supported by brackets 1 on the member 1 of the frame. The member 1 is shown partly broken away. This will be secured in any suitable manner above the tank containing the supporting liquid. The pots 2 are essentially the same, but carry feeders of different form. Each pot has a plunger-head 3 therein, supported by an arm 4, carrying a weight 5 and fastened by a pin 6 to the lever 6, which is fulcrumed at 6 on an arm 2, secured to the upper part of the pot. The cams 7 are rigid on the shafts 8, which are journaled inarms 8 on the member 1 of the frame.

Each shaft 8 is connected with suitable d-rivingpowerforrevolvingsame. (Notshown in the drawings.)

It will be seen that the revolution of the shafts 8 through the cams 7, acting under the free ends of the lovers 6, intermittently raises the plunger-heads 3, the weights 5 urging same normally downwardly. The office of the plunger-heads is to keep the paint agitated and in free-flowing condition.

The parts below the cooks 9 and 9 control the variety of the designs in which the paint forms upon the supporting liquid. In the form shown at the right of Fig.2 a tube 10 is threaded to the cock 9. The tube carries a wick 11, made of coarsely-woven wool, spun yarn, or other similar material. The wick reaches just into the surface a of the supporting liquid and furnishes a steady unbroken flow of paint, which, through the current of the supporting liquid, forms a Streaky coating upon same. This coating is carried by the current in the direction of the arrow. The next feeder has a grooved needle 12, fastened to the lever 13, which is fulcrumed at 14 on the arm 15 of the frame. The needle 12 is flared at the upper end in funnel shape, so as to catch the paint dropping from the cock 9. The free arm of the lever 13 is urged normally downward by the spring 16, secured to the same and to the arm 15. The cam 17 is rigidly mounted on the shaft 17, journaled in the arm 15. The shaft 17 is connected with suitable driving power for revolving same. (Not shown in the drawings.) The shafts 8 and 17 may all be connected by pulleys so as to be driven simultaneously. The cam 17 intermittently raises the free end of the lever 13 against the action of the spring 16, so as to give the needle 12 a vibratory motion, as indicated by the dotted lines. This scatters the paint in drops from the end of the needle, the same running down the groove in the side of the needle. The drops from the needle spread out in different shapes, sinkinginto the film already formed and some running together, so as to form a marbled surface in connectionwith the ground color furnished by the feeder to the right, before described.

The feeder at the left of Fig. 2 is in the form of an atomizer. This consists of a funnel 18, secured to the pipe 20 below the cock 9. The pipe 20 communicates with the airchamber 21, which is supported on the member 21 of the frame. The cover of the airchamber is a flexible diaphragm 22, which is held normally upward by the spring in the position indicated by the dotted line. A weight or plunger 2a is suspended above the diaphragm by the arm 25, which is slidingly supported in the bearing-sleeve 25 in the member 1 of the frame. The upper end of the arm 25 is curved, so as to permit the free rotation of the cam '7, and projects over same and under the free end of the lever 6 at 26. The pipe 20 has an extension 19, curved slightly upward and forming a drip-pan under the funnel 18.

It will be seen that when the plunger 2a is raised by the action of the cam '7 the chamber 21 fills with air, and when the plunger drops upon the diaphragm the air is suddenly expelled through the pipe 20, so as to scatter the paint dropping from the funnel in fine spray, which settles into the coating already formed by the other feeders. This being of a different color gives same the appearance of a fine cross-grain. The film is so thin that when pigments of about the same specific gravity are used its appearance will be the same on both sides, so that an article treated by bringing same in contact with the upper surface of the film will show in reverse the same design as that presented toward the artiele.

It will be seen that the different forms of feeders may be used singly or in combination and that the extent of flow from each may be regulated by the cooks, so that an innumerable variety of films may be formed. The speed and direction of the current will also in fiuence the character of the design. Vhen a certain current is used and the feeders have a certain adjustment, the film formed thereby will have the sam'e general character throughout, though varying in the specfic designs displayed in different parts. By the use of the first two feeders described an imitation marble finish may be applied with or without the feeder last described. By the use of the first and last feeders, omitting the second, an imitation wood finish may be applied.

It will be understood that the feeders may be used in series and may be arranged in any desired order for producing designs of differ ent general character.

In general my device embodies feeders for producing three distinct classes of finishthe first a streaky finish, the second a variegated finish formed of drops running together in different forms, and the third at finely-spottcd or veiled finish.

It is plain that the details of construction of my device may be altered in numerous ways without departing from the spirit of my invention. Itherefore do not confine myself to such details.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. In an apparatus of the class described, the combination of a tank containing a flowing supporting liquid; a paint-feeder having its feeding end in contact with the surface of said liquid, and adapted to feed the paint upon said surface in the form of a streaked film; a second feeder having a vibratory motion adapted to throw the paint in scattered drops upon said surface; and a third feeder adapted to throw a fine spray of paint upon said surface; substantially as and for the pn rposes specified.

2. In an apparatus of the class described, the combination of a tank containing aflowing supporting liquid; a paint-feeder having its feeding end in contact with the surface of said liquid, and adapted to feed the paint upon said surface in the form of a streaked film; and another feeder having a vibratory motion adapted to throw the paint in scattered drops upon said surface; substantially as and for the purpose specified.

3. In an apparatus of the class described, the combination of a tank containing a fiowing supporting liquid; at paint-feeder having its feeding end in contact with the surface 4. In an apparatus of the class described,
